SPECIFICA TIoN forming part of Letters Patent No. 682,884, dated september 17, 1901.

Application filed May 29, 1901.

To all whom z5 may concern:

. Be it known that I, THOMAS O. ORGAN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Feed- Water Purifiers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in feed-water purifiers.

The primary object of the invention is to provide improved means for supplying a feed-L water purifying compound to feed water heaters o1' storage-tanks such as provide a supply for locomotives and also to settling-tanks used in dye-houses,where pure water is required, avoiding the supply of acids to the. feed-pipes or feed-pump of boiler.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l shows in side elevation, with parts in section, the applicati-on of my improvements. Fig. 2 is an enlarged vertical sectional View.

Referring to the drawings, 1 designates the water supply pipe connecting with a city main, and 2 a feed-water heater, a portion 'only of which is shown and into which, at or, near its top, opens the pipe 1. Y

3 is a chemical-containing tank wherein is placed suitable acids for effecting the precipitation of all scale-forming particles usually present in feed-water. This tank is provided at its top with a valve-controlled charging-pipe 4, having a funnel 5,.and adjacent to said pipe is an air-cock 6, while in the bottom of the tank is a drain-valve 7. At or near its bottom tank 3 is connected by a water-supply pipe 8 with the main supply-pipe 1, the entrance of water through this pipe to the tank being controlled by a valve 9. The

tank 3 at its top has an outlet-pi pe 10,equipped with a valve 12 and opening into a valvecasing 13, adjacent to which is a sight-feedga-ge attachment 14. Within casing 13 is a Serial No. 62,406. (No model.)

the entrance of steam thereinto. When the water rises aboveA the working level, oat 16 will effect the closing of val ve 15, and thereby cut off the further supply of chemicallycharged Water. This closing of the valve by l the Water-levels 'in the tank will take place when water is not being drawn `o-that is,

when the force-pump is not working-and thus excess supply of chemicals to the Water lis'prevented. The discharge from tank 3 is controlled by valve 12 and is visible through thesiglIt-feed attachment 14. Y In practice valves 9 and 12 are closed, and after the tank 3 is emptied through drain- Yvalve '7 the latter isthen closed and chemicals are supplied through valve-pipe 4, the air-cock 6 being open during this charging. Then the valve of pipe 4c and also the cock 6 are closed and valves 9 and 12 are opened to permit a portion of the water passing through pipe 1 to travel through pipe 8, tank 3, and discharge-pipe 10. The water thus deiiected from pipe 1 enters the feed-Water heater or storage-tank or settling-tank, as the case may be, suciently charged with acid or waterpurifying compound to eifect the precipitation in the tank or heater of all scale-forming particles. Hence the water entering the feedpipes or the feed-pump is pure, all precipitation having occurred and theacids having been neutralized before the water enters the feed-pipes.

v The advantages of my invention are apparent. Among these may be noted that I avoid forcing large quantities of Water-purifying compounds into the feed apparatus or boiler, that this compound is admitted to the water Awhen the latter is at or below the Working line in cold-water-storage tanks or open feedwater heaters, and that if the attachment should be connected to a heater and the drips from the heating system should overflow the supply of the purifying compound is promptly cut 0E, preventing any excess of feeding such compounds and avoiding foaming in a steamboiler.

I claim as my invention- 1. The combination with a feed-water tank and the supply-pipe opening thereinto, of a receptacle containing a water-purifying compound connected to said supply-pipe and to said tank for automatically supplying thelatter with scale-precipitating compounds, and means actuated by the water-levels in the tank for automatically cutting o such supply, as set forth.

2. The combination with a feed-water tank and the supply-pipe opening thereinto, of a receptacle containing a water-purifying compound, a Valved connection between said receptacle and tank, a connection between the latter and said supply-pipe, a second valve in the connection between the receptacle and tank, and means for automatically actuating the same to cut off the supply from the receptacle to the tank, such means being controlled by the water-levels in the latter, as set forth.

3. The combination with a feedwater tank and the supply-pipe thereof, of a receptacle containing a Water-purifying compound, a valved pipe connecting said supplypipe and receptacle, an outlet-pipe leading from said receptacle to said tank, a sight-feed attachment Within such pipe, a valve-casing, a valve therein for automatically cutting o the sup ply from the receptacle, the pipe connecting said'valve-casing to the tank opening into the latter` below the working level, and a iioat in said casing for actuating the valve therein, as set forth.

4. The combination with a water-supply tank, and the supply-pipe therefor opening thereinto, of a chemical-containing tank having a water-supply connection at one end with said supply-pipe, and a water-discharge connection at its other end with said supplytank, and means actuated by the waterleve1s in the tank for automatically cutting oi such discharge when, the water in the supply-tank reaches a predetermined level, as set forth.

5. The combination with the water-supply tank, and the supply-pipe therefor opening thereinto, of a chemical-con taining tank having a water-supply connection at one end with said supply-pipe,a valved discharge-pipe1cad= ing from the other end ofsuch latter tank, a casing into which such pipe opens, a valve and iioat in said casing for automatically cut*- ting off the discharge from such pipe, and a pipe extended from said casing into said supply-tank having its yinner end bent downward below the working water-leve1, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
